ABSTRACT
As a contribution to solving environmental problems, some attempts at recycling waste into geomaterials have been carried out but only a few kinds of waste have a lower rigidity than that of soil particles. Therefore, deformation characteristics such as the compressibility of a soil mixed with waste must be clarified for use in an actual setting. In this study, a DEM program was developed, which can consider the compressibility of constituent particles. Then the soil compression mechanics caused by constituent deformable particles were investigated, by simulating a one-dimensional compression test of soil mixed with crushed EPS. As a result, it was confirmed that the developed DEM program could express the difference in the compression characteristics of soil and mixed soil. Moreover, further compression mechanics of soil mixed with deformable particles, recognized by the results of one-dimensional compression tests, could be estimated mechanically.
